Octal Bus Transceivers With 3-State Outputs - SN74HC245

SN74HC245 (ACTIVE)

Octal Bus Transceivers With 3-State Outputs

 

Description

These octal bus transceivers are designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements.

The devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.

 

Features

  • Wide Operating Voltage Range of 2 V to 6 V
  • High-Current 3-State Outputs Drive Bus Lines Directly or Up to 15 LSTTL Loads
  • Low Power Consumption, 80-μA Max ICC
  • Typical tpd = 12 ns
  • ±6-mA Output Drive at 5 V
  • Low Input Current of 1 μA Max
  • On Products Compliant to MIL-PRF-38535, All Parameters Are Tested Unless Otherwise Noted. On All Other Products, Production Processing Does Not Necessarily Include Testing of All Parameters.
